`Application Yfiled August 3, 1926. Serial No. 126,874.

This invention relates to la disk wheel and a dem'ountable rim therefor. Y l

An object of the invention is the provision of fa disk wheel having a demountable rim which may be readily removed lfrom the wheel lby the rotation of a crank,

vA further object of theinvention is the provision of a demountablerim for a -disk wheel in 'which an expandingianged shoe is controlled by aA crank for locking the rim to 'the felly of the wheel, the 'shoebeing slidable on rivets which 'not only support the `shoe but provide means for securing the diskedsectionslof the disk wheel.

This invention 2wi-l1`fbe best understood from a consideration of the following 'detailed description, vin view of the accompanying drawings forming apart of the speclifica't-ion; nevertheless it is to be understood that thel invention is not confined Ito the fdis- Closure,I beingl susceptible of such changes and modifications whichshall define no inaterial departure fromthesalient'features of4 the invention 'as expressed in the appended claims. f

filler 14 is secured position at the center and between and to the disks 10 and 1-1.

Disk 10 has alater'al curved flange`15 ex-A u tending for substantially the half Vof the periphery of said disk. Said iange is Vprovided with a groove 16 adapted toreceive a coextensive with the 'iian'ge 15. T he disk 11 adjacent its `periphery .is inV abutmentwith the -iange 15. The rivets 12 secure this engaged portionfof the disk ,10 to disk 111while the rivets 13 not only secure the remainingv portions of the disks 1() and 11 but space the remaining .portions of the vdisks from each other to permitmoveinentof a shoe 21...

The shoe isV curved .to conform to the curvature of the periphery of the rim 18 `and is-ofa length to :permitshifting of the shoe` thereby providing a space between the ends of theshoe and tliee'n'ds of the curvediangel l 20. The shoehas a flange 22 and a flange 23 of less width than the flange 22, the iianges beingconnected togetherA by a curved rimv 24 having' agroove 25. `Referring to FiguresG yto 8 inclusive, it will be seen that the groove is vin concentricy relation. with the plane.passingthroughthe center of the bead 17 of the :rim 18 andv at right angles to 4the Thei'anges`22 and 23 Aof 'the shoe 21 are provided with slots 26 located at acute angies to radii passingy through lthe rivets 13 and the rivets pass through said slots. By

this construction, :the shoe :is movable eccentrically relative'to the portion of the vrim 18 adjacent ythe shoeand away from the rim.`

Said shoe is located ,between portions of the disks 10 and 11 and is yadapted to seat At-he flange -19-of'dis`k 10 in 'a portion of lthe groove 25 of `tlie'shoe.

A4 crank 27 is'journaled in apertures in the v:disks 10 and 11jintermediate the tends ofthe shoe. Asquare Vhead 28-projects beby a'vsuitable wrench for rotating Ythec'rank.

A -rod 29 `is vpivotally connectedat 30 tov the crankl andv is received by a slee-ve 31 threaded intona -perforationlin a bolt 32. The sleeve isadjusted on .the rod'29 .between yondV disk k11and is 'adapted to'be engaged y Cil ' iiaiige 19 on disk 10.

the shoulders 33 and r)Che bolt is mounted in the flanges and Q3 ol' the shoe. Said shoe is cut away at at each side oi' the crank QT to permit movement et the shoe between the disks 10 and 11.

A locking spring 3G is secured to the outer face olf` disk 11 adjacent the crank 2T and has an opening 3T conforming to the shape ot the head QS in order that the head niay be received by the opening and hold the crank from turning. The spring may be pressed inwardly towards the disk 11 until the opeir ing registers with the cylindrical portion 3S ot the crank when the crank is tree for turning.

The disk 11 is provided with an opening 3S) and is ot' sullicient diameter to permit the usual valve stem Jr-O oi an inner tube to project above the outer edge oi the opening. A cap is adapted to be applied to the threaded end ot the valve stein to operate as :i dust cap.

A weight is secured in any approved manner to the disks, diaiiietrically opposite the crank 2T as a couiiterbalaiice.

A driving pin 51 on the rim .inserted through an opening in the flange 15 oi disk 10.

The operation of our device is as follows:

The rim 18 is so placed that the bead 17 will be engaged by the groove '16 ot the flange l5 on the disk 10.

The opposite side oit the rim is moved so that the bead 17 at this point will engage the The crank QT is rotated by the wrench which has been applied to the head 2Q. The rotation ot the crank causes the rod 29 to exert a pull on bolt 32 and since said bolt is connected to the shoe 21, said shoe is forced into engagement with the riin, said shoe being guided by the rivets 13 and the slots 2G.

Then the shoe is positioned, it 'forced up rigidly against the rim as the bead 1T ot the rini is seated under pressure iii the groove The riin springs away trom the telly ot the wheel adjacent the crank 2i" when the shoe has been released by a reverse rotation oit the crank.

It inust be borne in mind that the spring 3G must be depressed towards the disk 11 so that the opening 37 will be positioned at the reduced cylindrical portion 3S before the crank may be rotated, since the opening engages the head 2S and locks the crank troni rotation a't'ter the crank has been moved to releasing or locking position oi? said shoe.

The groove is displaced relative to a plane passing vertically and midway between the sides 22 and 28 of the shoe so that the shoe will grip the inner side ozt' the flange 19 on disk 10 and also grip head 1T ot the riin when the shoe is forced into place and this is true of the grooves Qfa'land 25'J as shown in Figures G to 8 inclusive.

in Figures 9 and 10, a modified forni oi the invention is shown and in which a crank QTl is journaled in apertures in the disks 10"L and 11"L intermediate the ends oit the slices. A square head 28 projects beyond the disk 11n and adapted to be engaged by a suitable wrench ioi rotating tliecrank. A rod 29u pivotally connected at 30 to the crank and has one end as shown at 46 inserted through a perforation in a bolt- SQR The bolt is mounted in llanges 22a and 23 of the shoe. A ring fli' mounted in a groove at the outer end ot' the rod 1:6 engages a shoulder in the bolt SEZ and maintains the rod against loss trein the bolt. A spring 4:5, embracing the rod etti, tends to exert a pre determined pressure between the bolt 32 and a shoulder L19 ioriiied on the rod 1lb. This spring all'ords a. cushioning eiiect and per mits an easier operation oi' the .locking device, especially when the wheel is covered with dirt or sand. As the sand works out the. riin is automatically tightened by the spring which :Forces the shoe outwardly. 'lhe spring eliminates the use ot an adjustiiieiit as shown in Figures i and 5.
